Does anybody know the turns ratio of the input transformer on the 361?
The manual happily describes the output transformer as 1:2, but completely ignores the input.  :(
 
1:1
white to grey:  724 ohms DCR
orange to pink:  881 ohms DCR

from 600 ohms source to 100k analyzer input, 1000 Hz
orange/pink "primary"  0.8 VAC :  white/grey "secondary" 0 .78 VAC
white/grey "primary" 0.8 VAC : orange/pink "secondary" 0.78 VAC
